数学函数在整个中学数学中占有重要的角色,它是学好数学的基础,函数的学习固然重要,它也是数学体系的中心思想,学好函数是提高学生对数学中的数量关系及思维逻辑关系认识的一次飞跃。目前初中数学函数是学生们最难理解的课程。函数的逻辑抽象性对初中生而言在学习函数课程中确实是一难题。本文就是在教学方法上给出了一些建议,以期在课堂中把学生的思维引入函数体系中,使学生们应用灵活多变的思维能力解决此难题。
Mathematical function occupies an important role in the whole secondary school mathematics. It is the foundation of learning mathematics. It is important to learn the function. It is also the central idea of the mathematical system. To learn the good function is to improve students’ understanding of the relationship between quantity and logic in mathematics A leap. At present junior high school mathematics function is the most difficult course that the student understands. The logical abstraction of a function is indeed a problem for junior high school students in learning function courses. This article gives some advice on teaching methods, in order to introduce the students’ thinking into the functional system in the classroom, so that students can apply flexible thinking ability to solve this problem.
